Following the instruction for the standardization of sodium hydroxide a student took 3.5 gms of KHP (MWt 204.2g/mol) and titrated the solution formed with the given sodium hydroxide solution. His buret volume read 1.85 mL at the start of the experiment and 24.65 mL when the phenolphthalein indicator turned pink. Show all calculations and logic for full points determine the strength of the sodium hydroxide solution.
Using Henry's Law to calculate gas solubility If air contains 78% N2 by volume, what is the solubility of N2 in water of 25oC and 1 atm (Henry's constant kH for N2 in H2O at 25oC = 7 x 10-4 mol/L.atm)?
What would be the equilibrium pH value of rainwater if atmospheric SO2 gas were its only dissolved constituent? Assume that the fugacity (activity) of SO2 gas in the atmosphere is 5 x 10-9 bar
a constant push of 250N is necessary to slide a crate weighing 400N along a 2.0-meter-long ramp. if the ramp rises 1.0m, what is the efficiency of the ramp.
The resulting equilibrium solution has a pH of 10.56. What is the Ksp of the salt at 22 °C?
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide.
A 250 g yo-yo is swung on the end of a50 cm string at a constant speed of 4 m/s. What is the centripetal force acting on the yo-yo?
How much Tris (1.0 M) (MW: 121.1 g/mol) and EDTA (0.2M) (MW: 372.2 ) solutions are used to prepare a 100ml of TE buffer (10mM Tris and 1mM EDTA)
